I'm only 50 years old, but I'm forgetting more than I used, getting confused easily, and hearing things that others don't. Could I have Alzheimer's?

It is normal to not be as quick in recall as we age, but becoming confused easily and hearing things others don’t is not normal aging. There are many reasons why you may be experiencing this including delirium (an acute condition such as from medications or illness). Have your physician do a complete exam and to also evaluate for any possible mental conditions.
